Abstract
An anti-loosening device for an inclined steel wire rope of a hoist is arranged below one side, which is close to the hoist, of the inclined steel wire rope and is characterized by comprising a base, an elastic mechanism, a sensor and a control circuit, wherein the elastic mechanism is arranged on the base, and can deform after the inclined steel wire rope looses to press down; the sensor is connected with the control circuit, is used for detecting deformation signal of the control elastic mechanism and transmitting the deformation signal to the control circuit; and the control circuit is used for controlling the normal work of the hoist, and can receive the deformation signal to control the hoist to stop working; and the anti-loosening device can accurately detect whether the steel wire rope loosens or not, can timely deal with the loosening condition of the steel wire rope; and the anti-loosening device for an inclined steel wire rope has simple structure and is safe and reliable.
Description
Technical field
The utility model relates to the steel rope locking device of winch, especially a kind of cable-stayed type steel rope locking device of winch.
Background technology
Known, self-lift is to adopt winch as promoting power, and the steel rope locking device of winch is to adopt mechanical limit switch mostly, the precondition that adopts mechanical limit switch is that an end of winch steel rope is to be fixed on the base of gig, specifically, mounting spring between steel rope and gig base is after steel rope is lax, spring shrinks and touches travel switch, disconnects the power circuit of winch.But for an end of the cable-stayed type steel rope of winch (during the steel rope tension with the angled inclination of horizontal surface) be raised the gig that thing is captiveed joint, if above-mentioned mechanical limit switch is set being raised between thing and the steel rope, it is disconnected then to occur erroneous judgement easily, and the signal wire (SW) of travel switch moves faults such as easy appearance broken string together along with being raised thing; Another kind method then is by conductor is installed below steel rope; conducting 24V safety voltage on the conductor; after steel rope is lax; conductor ground connection; after sending ground signalling to relay; controlling main motor shuts down; but make conducting resistance become big owing to there is the dust of grease and camp site environment easily conductive surface to be polluted on the steel rope; when the resistance deficiency so that during the voltage ground connection of 24V; control circuit is failure to actuate when causing steel rope lax; cause steel rope to twine extruding, damage equipment, in potential safety hazard.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of simple in structure, safe and reliable winch cable-stayed type steel rope locking device is provided.
The purpose of this utility model realizes by following technical solution:
A kind of cable-stayed type steel rope locking device of winch is arranged at the below of cable-stayed type steel rope near winch one side, it is characterized in that: comprise a base; One elastic mechanism is arranged on the described base, and is arranged to can produce deformation when described cable-stayed type steel rope is lax after pressing down; One sensor is connected with control circuit, is used to detect the deformation signal of described elastic mechanism, and deformation signal is transferred to control circuit; Control circuit is used to control the normal operation of winch, and can receive described deformation signal with control winch quit work.
Further, described elastic mechanism, comprise the cross bar that is arranged at cable-stayed type steel rope below, be arranged at the spring between cross bar two ends and the described base and be connected with described cross bar middle part and the induction pieces of downward extension, described deformation signal is the position signal of described induction pieces, described sensor is arranged on the described base of described induction pieces below, is used to detect the position signal of described induction pieces.
Further, described sensor is near switch or opto-electronic pickup.
The utlity model has following beneficial effect:
When relaxation appears in the cable-stayed type steel rope, steel rope vertical depression under the effect of gravity, utilize the weight of steel rope itself, drive the cross bar displacement vertically downward of elastic mechanism, at this moment be installed in the induction pieces proximity transducer on the cross bar, sensor flows to control circuit with the position signal of induction pieces, the control winch quit work after control circuit received this signal, the utility model integral structure is simple, reasonable in design, cost of manufacture is low, compared with prior art, whether the utility model can detect steel rope exactly lax, when steel rope is lax, can in time control winch and quit work, avoid the lax back of steel rope winch still to work on, and cause steel rope to twine extruding, damage equipment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the schematic diagram of the utility model control circuit.
The specific embodiment
With reference to shown in Figure 1, a kind of cable-stayed type steel rope locking device of winch comprises base 3, elastic mechanism, sensor 5 and control circuit.
Base 3 is arranged at cable-stayed type steel rope 6 near under winch one sides, and said here cable-stayed type steel rope 6 is during for tension and the angled bevelled steel rope of horizontal surface, and shown in the figure is bifilar cable-stayed type steel rope; Elastic mechanism is arranged on the base 3, comprise the cross bar 1 that is arranged at cable-stayed type steel rope 6 belows, be arranged at spring 2 between cross bar 1 two ends and the base 3 and the induction pieces 4 that is connected and extends with cross bar 1 middle part downwards, wherein cross bar 1 employing diameter is the steel pipe of 8mm, the elasticity modulus of spring 2 can be adjusted according to the weight of steel rope 6, and induction pieces 4 is for long: the square iron block of 10mm, wide: 5mm, thickness: 3mm; Sensor 5 is arranged on the base 3 of induction pieces 4 belows, is connected with control circuit, is used to detect the position signal of induction pieces 4, and position signal is transferred to control circuit, and concrete sensor 4 is an opto-electronic pickup; Control circuit is used to control the normal operation of winch, and the position signal that can and can receive induction pieces 4 quits work with the control winch.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modification, all should still belong in the scope that patent of the present invention contains.
